The text snippets are all related to skripsis, which are academic papers written by students as a requirement to complete their degree programs. These skripsis focus on the phenomenon of code mixing and code switching in language use. Code mixing refers to the use of multiple languages or dialects in a single conversation, while code switching refers to switching between languages or dialects during a conversation. The research found that code mixing commonly occurs in daily communication and it serves as a bridge between people who speak different languages. The types of code mixing can vary, with intra-sentential being the most common and involving a change of pronunciation being the least common. The skripsis also explore the grammatical items and functions of code mixing and code switching, as well as their usage in teaching and learning processes. It is an interesting topic of study, as it sheds light on how language is used and the factors that influence code mixing and code switching.
